Product details

32 MHz Cortex-M0+ with 192 KB flash — the battery-life trade-off

The STM32L071CZT6 runs an ARM Cortex-M0+ core at 32 MHz, with 192 KB of program flash and 20 KB of SRAM — enough for a modest sensor-fusion stack or a single-protocol wireless node without external memory. The 6 KB on-chip EEPROM holds calibration constants or configuration data that survive power loss without a separate serial EEPROM on the board.

Industrial temperature grade and 48-LQFP footprint

The 13-channel 12-bit ADC covers multi-sensor analog front-ends without an external multiplexer; the internal oscillator eliminates the crystal for applications that can tolerate the ±1% accuracy.

Frequently asked questions

What is the closest functional alternative to STM32L071CZT6?

The STM32L151CBU6A is a Cortex-M3-based sibling with the same 37 I/O count and 32 MHz speed, but it adds USB, capacitive sensing, and a 2-channel DAC. The M3 core draws more current at the same clock, so the swap trades battery life for peripheral headroom. The 48-LQFP package is the same footprint, but the pinout is not identical — a board spin is required.

What compliance documentation is available for STM32L071CZT6?

The part is ROHS3 compliant. No UL, IEC, or REACH certification is listed in the manufacturer's standard documentation for this order code.
